摘　　要：本文论述的基于Z80 CPU的微机型晶闸管交流控制器具有以下与众不同的特点:a.采用“预定状态监视法”检测自然换相点,使自然换相点的检测硬件和软件都达到最简;b.采用“串行定时方式”来控制六相触发脉冲的延迟,不仅节省了CTC通道,而且减少了响应时滞和确保了触发顺序在任何情况下都不会被打乱;c.用软件控制直接输出双窄脉冲,简化了触发脉冲输出电路。A practical digital trigger based on a Z80 microprocessor is presented. The trigger is useful for any type of thyristor converter.The trigger is characterized by the following features: fast response, high accuracy, short time delay and wide range of triggering angles. With simple hardware and software, it is highly reliable.
